Airway suctioning procedure and its complications in subjects with invasive mechanical ventilation in intensive care units of a public hospital in the Autonomous City of Buenos Aires: a descriptive observational study
Abstract
Objective: To describe the airway suctioning (AS) procedure in subjects with invasive mechanical ventilation, report the associated complications, and assess the degree of compliance with the recommendations established in the Clinical Practice Guideline (CPG) of the American Association for Respiratory Care (AARC). The secondary objective is to investigate whether there are discrepancies between the AS procedures that lead to complications and those that do not.
Materials and methods: An observational and prospective study was conducted on subjects over 18 years of age who received invasive mechanical ventilation (IMV) through an endotracheal tube and were attended by respiratory and physical therapists at the time of the observation. Observations were carried out during the routine care of the subjects using a checklist based on the recommendations of the AARC CPG, and complications were recorded.
Results: A total of 104 observations were conducted on 48 subjects. Fifty-one percent of AS procedures met the criteria established by the CPG, and at least one complication occurred in 76% of them. Blood pressure (BP) changes were the most prevalent complication. AS procedures that met the criteria showed a complication rate similar to those that did not (77 % vs. 76 %, p=0.90).
Conclusion: It was observed that the recommendations by the AARC CPG were partially followed. Furthermore, complications associated with AS procedures, particularly changes in BP, were frequent.
